11. Development and application of laser diagnostics - from laboratory devices towards practical combustion engines
Sammanfattning : For many decades, research work on combustion has been focused on improving combustion efficiency and reducing harmful emissions. Laser diagnostics is one of the best ways to investigate the combustion process and emission formation as it is non-intrusive and it has high spatiotemporal resolution. LÄS MER
12. Factors that Influence the Biochemical Methane Potential (BMP) Test : Steps towards the Standardisation of BMP Test
Sammanfattning : Anaerobic digestion (AD) has gained increasing attention nowadays as an approach for both waste treatment and renewable energy generation. Currently, many different types of materials can be used as feedstock for biogas production via AD process, but their biodegradability (based on methane yield, BDCH4) and potential to produce biogas might vary significantly, and these properties are key parameters that should be taken into consideration for economy, design and operation of a full-scale biogas plant during the selection of potential feedstock.

13. Characteristics of BVOC emissions from a Swedish boreal forest : Using chambers to capture biogenic volatile organic compounds (BVOCs) from trees and forest floor
Sammanfattning : Plant-emitted biogenic volatile organic compounds (BVOCs) are a large group of hydrocarbons released by plant leaves, bark, flowers and fruits into the atmosphere and from plant roots into the soil. BVOCs have important physiological and ecological functions, such as mediating within-plant and plant-plant communication, defense against herbivores attack, protection against heat or other oxidative stress, attracting pollinators etc. LÄS MER
14. Between Modern Schooling and Cultural Heritage : Education and Ethnicity in Southwest China
Sammanfattning : Since the late 1970s, China has experienced remarkable socioeconomic development. The trend towards marketisation and modernisation overturned culturally-rooted lifestyles, and more and more ethnic minorities in China have started to regard their traditional cultures as irrelevant to their livelihoods and future and chosen to move away from them.

15. Coherent Multidimensional Spectroscopy: Development of Efficient Data Acquisition and Analyses of Quantum Dot 2D Spectra
Sammanfattning : Coherent multidimensional spectroscopy (CMDS) is the most complete nonlinear optical technique based on the interaction of multiple short laser pulses with matter. It has grown to play a significant role in studies of optoelectronic materials and pigment protein complexes. LÄS MER
